Doesn't work on Firefox 8 / 9 + Firebug 1.9.0 Rated 1 out of 5 stars

I work a lot with XML based web services, and this one looks promising.
Any plans for an update to make it work with Firefox 8 / 9 + Firebug 1.9.0?
That would be awesome.
Will post more on the support site, it's more convenient (

This review is for a previous version of the add-on (1.1.1-signed). 

What kind of update would you want, and how do you use it with XML?

Also, a 1.2 version has just been released here with support for the latest versions of Firefox and Firebug.
